Released by the heating device (burner) heat transfer by radiation is first absorbed waterwall waterwall Boiling water, a large amount of steam into the drum for water separation (excluding DC furnace), separated saturated steam enters the superheater , and it continues to absorb the top horizontal flue furnace by radiation, convection, heat of the flue gas flue of the tail, and the superheated steam to reach the required operating temperature. Power generation boilers are generally provided with a reheater, it is used to heat the steam through the high pressure cylinders acting reheater go out of the reheat steam, the low pressure cylinder to continue to generate power. Popular terms, the steam boiler is to absorb combustion heat of the fuel into the water some parameters (such as pressure, temperature, etc.) of the steam device. Boilers and boiler furnace divided into two parts, the pot is filled with water to a metal container, partially combusted fuel furnace, the heat absorption of the water inside the pot furnace fuel combustion converted to steam, with the basic principles of almost boiling water, the pot equivalent kettle, oven stove equivalent. 1, by fuel, our existing steam boiler fuel that can be used are: gas boilers, coal-fired boiler, oil-fired boiler, electric heating boilers, nuclear boilers, waste heat boiler, etc., of which the first four of the most common.
Boiler is how the classification? Press export steam parameters of how to classify? Classification of the boiler is very extensive concept from different angles have different classification, can be classified by application area, according to the export media classification, but also by the pressure of the boiler classification. If the classification parameters according to the steam outlet, then find out which parameters steam boiler, wherein the boiler comprises evaporation, steam pressure, steam temperature etc., and is classified according to the main points of the outlet steam pressure: low pressure boiler (P <2.5MPa ), pressure in the boiler (22.5
Gas boiler installation and preparation requirements of (a) the preparatory work before the installation of a boiler installation must be installed by the unit has installed a license .. The installer must be familiar with "Boiler Safety Technology Supervision", and carefully read the installation instructions and other random technical documents. 2, a mounting position: 1) as close as possible to install a boiler steam, hot site, to facilitate shortening the hot water and steam pipes, reducing capital costs, reducing the pipeline heat loss. The installation site should be water supply, sewage convenience. Burning light diesel oil, heavy oil residue and the boiler must be closer to the oil reservoir; burning natural gas, town gas boiler must be easy to close the gas source. 2) boiler room layout should follow the "Boiler Safety Technology Supervision" relevant provisions "boiler room", to be well-lit, well-ventilated, no ground water, ease of operation and maintenance, boiler room must be equipped with at least two fire extinguishers 1211. 3) Check the boiler foundation, prepare the boiler in place. 3, equipment acceptance: acceptance by conduct an inventory purchase contract or supply list. 4, lifting large boiler: not less than 1.1 times the lifting equipment of large weight of the boiler, two lugs for the lifting jack top or at the bottom edge away slowly, not to any other parts of the lifting or addendum to avoid damage to the boiler. (Ii) installation requirements: 1, the main steam line installation requires the main steam lead pipe height is generally greater than 0.5 m, the bending radius should be greater than or equal to 5 times the diameter of the pipe, the pipe should be installed at the lowest trap, preventing water pipe, It should be a main steam pipe insulation. 2, a main return pipe installation requirements should the main return pipe elbow minimize installation, to facilitate the mounting operation of the valve, piping should be insulated. 3, the hydrostatic testing relief valve, the safety valve should be installed in the exhaust pipe, the exhaust pipe connected to the straight pipe outdoor safety. 4, should be connected to a sewage outfall tank or other security, the pipe should be secured to prevent shifting or counter scald accidents blowdown. 5, railings, stairs (with large oven) after the positioning by drawing the boiler installation. 6, water table must be installed to the lighting device, easy to install or inspection.
Such as hotel Home Hotel Group is one of the three major brands, in 300 cities in the country has nearly 2,000 hotels. Home Inns has won China Golden Pillow Award for Best Chinese economy hotel chain brand award, in 2014, Home Inns brand value of $ 420 million of selected China's top 100 brands. April 4, 2016, BTG hotel groups such as the privatization of the hotel purchase transaction has been completed delivery. In mid-2016, as a Beijing hotel with our preliminary communication, the urgent need two boilers work of heating and hot water supply. I related technical engineers and recommend it to calculate the number and size of the boiler on the hotel room as hotel Willy sharp V6-99 two models.Free Chat
